/*
 *** Javascript Client for the Meetup API ***
 * This is an example for how to access data from the Meetup site
 * for client-side applications. It uses jQuery to handle the AJAX requests
 * (note that to avoid conflicts, the jQuery object has been aliased to j$)
 * and create callback functions so that you can make the request from outside
 * domains. You can hot-link this script from your site, or use your own
 * client code.
 *
 * For demo purposes, links that are signed by meetup.com do not require an API key;
 * for all other general API usage, a valid key must be provided with all requests.
 *
 * To get more details on request types, formats, parameters, and responses, see
 * the detailed API documentation at meetup.com.
